My car has the BMW Professional radio and recently the display started to go blank. It would last 30 seconds or up to 10 minutes. My dealer ordered a new radio and installed it under warranty. We I go the car back, the chimes were incredibly loud. Additionally when using the Bluetooth, the volume control was at the highest setting and the radio's volume knob no longer will adjust the volume for the Bluetooth. The radio itself works fine. My dealer says BMW is researching the problem and they will get back to me. It's been two days. Anyone experience anything like this?
